I. [Product Description]
OPSS-PEG-Poly-Ornithines is a multifunctional amphiphilic block copolymer that combines the high reactivity of ortho-pyridyl disulfide (OPSS), the biocompatibility of polyethylene glycol (PEG), and the charge characteristics of polyornithine. As an organic intermediate or pharmaceutical intermediate, it can achieve precise conjugation through dynamic disulfide bonds and is of great value in biological conjugation, nanocarrier preparation, and catalyst support construction.

III. [Application Areas]
    1. Biomolecular Conjugation: Realize the controllable modification of biological macromolecules such as proteins and polypeptides through the specific reaction between OPSS groups and thiol groups.
    2. Nanomaterial Preparation: Serve as an amphiphilic polymer template for loading hydrophobic molecules or constructing functionalized nanoparticles.
    3. Polymer Self-Assembly: Utilize the cationic characteristics of polyornithine and the shielding effect of PEG to form stable micelle or vesicle structures.
    4. Surface Functionalization: Modify material surfaces to improve hydrophilicity and anti-non-specific adsorption performance.
    5. Catalyst Support: Fix metal catalysts through the coordination ability of polyornithine to enhance catalytic efficiency and recyclability.
